Chandra X-ray Image of SNR 0509-67.5
A Chandra X-ray Observatory image of the supernova remnant SNR 0509-67.5 in
the Large Magellanic Cloud. The lowest energy X-rays are shown in red, the
intermediate energies are green and the highest energies are blue. In 2004,
scientists used Chandra to show that SNR 0509-67.5 was likely caused by a
Type Ia supernova, using an analysis of the elements, such as silicon and
iron, that were detected. A Type Ia is thought to result from a white dwarf
star in a binary system that reaches a critical mass and explodes. In the
new X-ray study of SNR 0509-67.5, spectra from Chandra and ESA's XMM-Newton
Observatory were used to calculate the amount of energy involved in the
original explosion, using an analysis of the supernova remnant and
state-of-the-art explosion models.

Illustration of Light Echoes and a Supernova Remnant
This sequence of artist's illustrations begins with a view of a bright,
massive star in the center, surrounded by several dust clouds. A bright
flash of light marks the destruction of the star in a supernova
explosion. As time passes the supernova dims and its light spreads
outwards, eventually reflecting off the dust clouds to create light
echoes. A supernova remnant eventually appears at the site of the supernova
explosion, and increases in size with time.

Light Echoes from the Supernova that Produced SNR 0509-67.5
This sequence of images shows light echoes from the supernova explosion that caused the remnant SNR 0509-67.5 to form. This CTIO 4m telescope optical image shows light from the original supernova explosion that has bounced off dust clouds in the neighboring regions of the Large Magellanic Cloud (the light echoes are shown in blue and stars in orange). The light from these echoes travels a longer path than the light that travels straight toward us, and so can be seen hundreds of years after the supernova itself. The 5 images were taken between 2001 and 2006 and are shown separately in a time-lapse movie.

Optical Panoramic Image of the Large Magellanic Cloud
This panoramic optical image of the Large Magellanic Cloud (LMC) is from
the Magellanic Cloud Emission Line Survey (MCELS), obtained with the University of Michigan's 0.9-meter Curtis Schmidt telescope at CTIO. Emission lines of hydrogen (H-alpha) are red, singly-ionized sulfur is green and doubly-ionized oxygen is blue. The image
highlights regions of star formation in the LMC, including supernova
remnants and giant structures carved out by multiple supernovas.
